| Abstract: | Mixture of thermoelectric Bi₂ Te₃ and ferromagnetic Ni powders was spark-plasma-sintered to prepare bulk composites with different Ni content (0.5 and 1.25 at.%). Hexagonal Bi₂ Te₃ , cubic Ni and trigonal NiTe₂ phases coexist in the composites. The Bi₂ Te₃phase forms matrix of the composite, whereas the Ni and NiTe₂ phases corresponds to filler. The filler is formed by Ni@NiTe₂ ("core-shell") inclusions. Forming "core-shell" inclusions is due to high-temperature diffuse redistribution of Ni during the composites sin-tering |
